When the moon moves directly between the Earth and the sun, it casts a dark shadow on Earth producing this type of eclipse.
What is solar?
100
*DOUBLE JEOPARDY* Compare the Earth's rotation to its revolution. Include the time for each.
Rotation is the turning, or spinning, of Earth on it’s axis (24 hours). Revolution is the motion of Earth around the Sun (365 days)
100
* DOUBLE JEOPARDY* In this view, Earth is a motionless sphere at the center of the universe.
What is geocentric?
100
This planet is closest to the sun and has the fastest orbit (about 88 days)
What is Mercury?
100
Daily changes in the elevation of the ocean surface.
What are tides?
200
When the moon moves within Earth’s shadow (Earth is between the sun & moon), it produces this type of eclipse. It occurs during full moon phases (not every time).
What is a lunar eclipse?
200
The slight movement, over a period of 26,000 years, of Earth’s axis.
What is precession?
200
In this model, the sun is the center of the universe and the Earth and other planets orbit around it.
What is heliocentric?
200
* DOUBLE JEOPARDY * List the planets in order from the sun.
What is mercury, venus, earth, mars, jupiter, saturn, uranus, neptune, pluto
200
The tendency of an object to resist a change in motion (at rest, stay at rest...in motion, stay in motion in @ same speed & in the given direction)
What is inertia?
300
Compare perigee and apogee.
Perigee: the point when the moon is closest to Earth Apogee: the point when the moon is farthest from Earth
300
The rocking, swaying, or nodding motion in the axis of Earth's rotation.
What is nutation?
300
Kepler developed three laws of planetary motion. This was his first law.
The path of each planet around the sun is an ellipse, with the sun at one focus – the other focus is symmetrically located at the opposite end of the ellipse (law of Ellipses)
300
Compare Neptune's orbital speed and time it takes to orbit the sun compared to Earth.
Neptune has an orbital speed of 5 km/s and takes 165 years to make 1 revolution around the sun – the longest of any planet
300
Occur when the tidal range is much less, when the moon is at 1st quarter & 3rd (last) quarter; the gravitational forces of the sun & the moon are at right angles; their forces partially offset each other & the tidal range is LESS
What are neap tides?
400
On the mini whiteboard, draw and label the phases of the moon about the Earth. Shade in the area that cannot be seen. Draw the sun as well.
new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third/last quarter, waning crescent
400
The point in space around which two objects orbit. This is why it is usually not in the center of two bodies.
What is the barycenter. The masses are typically not equal, therefore the force of gravity is not equal & the barycenter must be closer to the larger planet in order to balance the forces & orbit.
400
Galileo constructed his own ____________. This is one discovery he made.
What is telescope? Contributions/Discoveries: Four satellites (moons) orbiting Jupiter (therefore, Earth was not the only center of motion); Planets are circular disks and are Earth-like; Venus has phases just like the moon – so Venus must orbit the sun; The moon’s surface is not smooth; The sun has sun spots (dark regions)
400
This planet is the sixth planet from the Sun and the most distant that can be seen with the naked eye. It is best known for its fabulous ring system that was discovered in 1610 by the astronomer Galileo Galilei.
What is Saturn?
400
Draw the tilt of Eath's axis, its revolution about the Sun, and the winter/summer.
See diagram.
500
Describe the moon's surface, its mass compared to the Earth, and its gravitational pull compared to the Earth's.
The moon's surface is full of craters; it is about 1/4 the size of Earth, the gravitational attraction on the moon is 1/6 that of Earth
500
The center of a huge rotating system of planets, their satellites, and smaller bodies is this. It is or is not stationary? Why?
What is the sun - it's not stationary. The pull of other planets.
500
Sir Isaac Newton was the first scientist to formulate and test this law. This is how distance and mass affected it.
What is the law of universal gravitation. Gravitational force decreases with greater distance and increases with greater mass
500
This is the fourth planet from the Sun. Named after the Roman god of war, and often described as the “Red Planet” due to its reddish appearance.
What is Mars?
500
Compare fusion and fission.
Fusion: Particles “fuse” together to create energy; found on the sun & stars Fission: Particles split to create energy; Found in nuclear reactors splitting atoms to create energy
